Dürr Technik HA-062 Multi-Head Oil-Free Air Compressor Station

Overview

The Dürr Technik HA-062 is an engineered oil-free air compressor station designed for continuous, contamination-sensitive laboratory and analytical instrument supply applications. It operates on a precision-machined piston compression principle—ensuring zero hydrocarbon carryover and eliminating the risk of oil vapor ingress into downstream pneumatic systems. Unlike single-head compressors, the HA-062 integrates a rigid 55-liter ASME-stamped air receiver tank with standardized mounting interfaces, enabling the simultaneous installation of up to three independently controlled compressor heads. This modular architecture allows users to scale total volumetric flow output linearly while maintaining consistent pressure stability and ISO 8573-1 Class 1:1:1 compressed air quality (oil-free, particle-free, moisture-controlled). The system is purpose-built for powering high-precision instrumentation—including gas chromatographs (GC), mass spectrometers (MS), laser-based particle sizers, and automated sample handling platforms—where trace-level oil, particulate, or humidity can compromise calibration integrity or detector response.

Key Features

• Modular multi-head platform supporting up to three synchronized piston compressor units mounted directly onto a single 55 L stainless-steel air receiver
• True oil-free operation certified per ISO 8573-1:2010 Class 0 (ISO 8573-1:2010 Annex B), verified by independent third-party testing
• Selectably integrated desiccant drying module achieving dew points as low as –40 °C (–40 °F) at 10 bar, configurable for critical low-humidity applications
• Multi-stage filtration system with final coalescing and adsorption filters rated for 0.01 µm or 0.1 µm particle retention (user-selectable during specification)
• Integrated pressure regulation and redundant safety valves compliant with PED 2014/68/EU and AD 2000-Merkblatt W2
• Low-vibration motor mounts and acoustic enclosure reducing operational noise to ≤62 dB(A) at 1 m distance

Sample Compatibility & Compliance

The HA-062 delivers compressed air meeting stringent purity requirements for regulated analytical workflows. Its output satisfies ISO 8573-1 Class 1:1:1 (solid particles ≤0.1 µm, water content ≤5 mg/m³, oil content ≤0.01 mg/m³) when equipped with optional 0.01 µm filtration and desiccant drying. This level of purity is essential for USP <41>, EP 2.6.27, and ASTM D6304-compliant gas supply systems. The unit’s construction materials—including FDA-compliant elastomers, electropolished stainless-steel wetted surfaces, and non-outgassing internal coatings—support GLP and GMP environments. All electrical components conform to IEC 61000-6-2 (EMC immunity) and IEC 60204-1 (machine safety), with CE marking affixed per Machinery Directive 2006/42/EC.

Software & Data Management

While the HA-062 operates as a standalone analog-controlled station, it features a digital I/O interface (0–10 V / 4–20 mA) compatible with centralized building management systems (BMS) and laboratory infrastructure monitoring platforms. Real-time parameters—including discharge pressure, motor current draw, runtime hours, and filter service intervals—are accessible via front-panel LED indicators and relay outputs for predictive maintenance alerts. For facilities requiring audit-trail capability, optional integration with Siemens Desigo CC or Schneider EcoStruxure Building Operation enables timestamped event logging aligned with FDA 21 CFR Part 11 electronic record requirements. No proprietary software is required; configuration and diagnostics are performed using standard Modbus RTU protocol over RS-485.

Applications

• Primary air source for GC-FID, GC-TCD, and GC-MS carrier and detector gas supply lines
• Pneumatic actuation in automated liquid handling workstations and robotic sample preparation systems
• Zero-air generation for ambient air monitoring analyzers (e.g., NO_x, SO₂, ozone calibrators)
• Pressurization of cleanroom HVAC make-up air systems requiring ISO Class 5–7 air quality
• Supply air for optical interferometry tables, scanning electron microscope (SEM) chamber purge, and laser cavity cooling loops

FAQ

Can the HA-062 be configured for continuous 24/7 operation?
Yes—the compressor heads are rated for >20,000 hours MTBF and include thermal overload protection, automatic condensate drainage, and duty-cycle optimization logic.
Is the 55 L receiver tank certified for pressure vessel compliance in North America?
The tank carries ASME Section VIII Div. 1 stamp and CRN registration for all Canadian provinces and U.S. states accepting ASME certification.
What maintenance intervals are recommended for the filtration and drying modules?
Desiccant cartridges require replacement every 6,000 operating hours; 0.01 µm final filters every 12 months or 8,000 hours—whichever occurs first—under typical lab loading conditions.
Does the HA-062 support remote monitoring via Ethernet or Wi-Fi?
No native Ethernet/Wi-Fi interface is included; however, third-party IoT gateways with Modbus TCP conversion can be deployed for cloud-based telemetry without modifying OEM hardware.
Can individual compressor heads be serviced without shutting down the entire station?
Yes—each head is isolated via dedicated ball valves and check valves, permitting hot-swapping under load with no interruption to downstream air supply.
